DHTML Menu

DHTML Menu adds dynamic functionality to the menus of your site. Ordinarily, reaching the child elements below an item requires you to visit its page. With DHTML Menu, clicking on an item with child elements will expand it without leaving the page, saving time. You can reach the actual page of such an item either by double-clicking on it or visiting the small extra link that will be shown right below it when expanded.
DHTML will be used for all menus by default, but can be switched off for specific menus.
